Well my husband who is not 34, quit smoking his almost 2 pack of Marlboro Mediums, over 4 years ago. Our son who was then 5, suffers from allergies and asthmatic symptoms. And the doctor told my husband that even though he smokes out side he is still bringing in the smoke/allergans off of him and his clothes, and that still passes on through our son. So he soon quit just for the health of our son. It was pretty hard ar first for him, but cold turkey was his only way he could do it. He tried some kind of thing he got from the flea market that he put on the end of his cigarette, that was suppose to help him quit, but it didn't. So his only method was purely just WILL POWER. After abour 6 months to a year he couldn't even stand the smell of a cigarette. He works with a guy who smokes daily, and it doesn't bother him at all and he is not tempted. Good Question!
